# NousResearch/hermes-agent · TTS audio container mismatch and Opus conversion patches

## Open now

- Nothing open on GitHub.

Several TTS providers (Edge, Piper, MiniMax, xAI) were saving non-Opus audio under .ogg extensions, breaking Telegram voice bubbles and on-device transcription. Patches add magic-byte container detection and proper transcoding to Opus before delivery.

## TL;DR

- 11 member(s): 0 open issue(s), 3 closed issue(s), 0 open PR(s), 1 merged PR(s), 7 PR(s) closed without merging.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `partially_resolved` · deciding PR(s): `pr-73507`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.16`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #36131: \[BUG\]Audio attachments cached with wrong .ogg extension (real format MP4/QuickTime+AAC) → on-device transcription fails
- #57048: Edge TTS provider silently saves MP3 bytes under a .ogg extension when given an explicit .ogg output_path (breaks Telegram voice bubbles)
- #58845: \[Bug\]: Piper TTS writes raw WAV to .ogg output path — Opus conversion skipped, Telegram shows 0-second voice bubble
